Постоянно Kubuntu 16.04 катастрофического отказа

У меня есть новая установка Kubuntu 16.04, все отказывает: Konsole, Firefox, плазма, границы нескольких раз окон исчезают и нет никакого пути, как больше управлять им. Я имею к ssh от другой машины и вызываю перезагрузку..

Попробованный для переустановки его, та же проблема снова, он - просто я, или у кого-то еще есть та же проблема? Ниже файл журнала:
